Hematite | Properties, Formation, Uses, Occurrence
Composition: Hematite consists of iron (Fe) and oxygen (O) atoms, with two iron atoms bonded to three oxygen atoms in each formula unit (Fe2O3). Iron Content: Hematite is a rich source of iron, typically containing about 70% iron by weight. This high iron content makes it an important ore for iron extraction and steel production.
